What should tie-in drains be used for when installing dry systems?

Tie-in drains are specifically designed to ensure proper drainage in dry pipe sprinkler systems. These systems are typically filled with pressurized air or nitrogen, and the tie-in drains play a crucial role in managing any water that may inadvertently enter the system. Proper drainage allows for the efficient functioning of the sprinkler system, ensuring that, in the event of activation, the pipes are free from unnecessary water which could cause premature discharge or other operational issues.

When implementing dry systems, it is essential to maintain their integrity and functionality. The tie-in drains help prevent any hazards that could arise from water accumulation, which can lead to corrosion, blockages, or in some cases, system failure. By ensuring that moisture is effectively managed and eliminated through drainage, the reliability and efficiency of the dry system in protecting against fire hazards are upheld.
